So,
Today I was messing around with GO Launcher EX and GO Locker, and I didn't like the performance, at all...so I did a search and found an app called spare parts that was supposed to help the animation speed, after a while of messing around, I noticed that my display wasn't nearly as bright as it was an hour ago. I checked and made sure that the display brightness setting was set to 100%, and that auto-adjust screen power was turned off, and the display was still about half as bright as when I started today.
How can I test if I messed something up? Or is this normal for a AMOLED display? Is there an app I can download that will force the brightness to go to 100%, to see if some app is messing with it? What the heck is going on.
Emmmmmooooo rrraaagggeee!!!
So I got a app that controls brightness , and in fact confirmed that the default controls were only boosting brightness to around 80 percent. What can affect the settings like this? Using automatic brightness, or changing the brightness through anything but this app leaves the screen dimmer than it normally is. I can't even use the touchwiz settings widget.
Interesting.
So, to further report on this odd behavior,
After further investigation, the brightness with auto-brightness seemingly drops light output further than the "0" setting in my brightness app, and further than the slider allows manually adjusting via the settings>display panel. Odd.
So,
I disabled all auto-brightness via the settings in the TouchWhiz apps (read: the browser and the video/audio player), and was just controlling brightness via the app I installed.
Later today, i turned on auto-brightness again via the Power Saving widget, and the issue where the screen dims farther than any manual settings allowed was gone. Again, i only have an issue with max brightness now-- using both the system settings panel to adjust brightness as well as using auto-brightness via both the power saving widget as well as the system settings panel.
So, in summary: the max brightness issue remains, and i can only set it to about 80% without using the brightness app i installed (the app allows me to set it to 100%....where as in the system settings, the slider goes to 100%, and stays at 100%, but the screen looks like its at about 80%. Using the brightness app i installed allows me to boost it back to 100%, but as soon as i change the brightness in the system settings app, or the power saving widget, it maxes out at 80. The slider moves all the way to 100%, but i'm only getting 80% brightness).
Note:
I have no apps installed that affect brightness...0. None of my apps have anything remotely having to do with the display, audio, or it's settings.
Maybe you can help me?
I turned off the auto brightness in the system settings/display/brightness but it seems that the screen starts to dim (sometimes). I hate this...I have to touch the screen to retain brightness. I don't want auto dimming...I want the level I set (which is about half way on the slider).
Where can I find a master override?

Adjust screen timeout. This happens when your screen is going to automatically turn off

Thanks... I'll check it out.
Also in display settings uncheck "auto adjust screen power"
Was there ever a solution to this? I am now starting to get this issue of screen will not respond to 100% brightness...and the option to change display brightness is greyed out in settings. It seems to be a problem with 'power savings' which I would like to completely remove from my phone as even when I turn it off, it is keeping me from adjusting my screen brightness when below 20% battery...and with my 5400 mah battery 20% is a full 8 hour day left...really irritating...only way to solve is to charge above 20%...or go enable power savings, then disable it again...but problem returns every time the screen goes off.
When using my phone, there is one brighter screen mode that occurs when actively using the phone, and then there is a idle dimm mode that occurs after about 30 seconds of idle time. Is it possible to control the brightness of the idle screen mode and possibly set it to 0? Is there an app advanced enought to do that?
I am basically using the phone as an mp3 player at night and I have to keep the phone awake and the screen on otherwise the wifi starts to stutter, but the default dimmness of idle mode is far too bright, so a way to keep the phone awake without emitting light is what I am after, but only on idle mode because otherwise I am not able to see and control the screen.

I notice some roms when booting have a low brightness state thats lower than brightness 0, also when the phone is about to turn its screen off it also dims first. Also dims when left idle when charger plugged in.
Whilst dimmed I can see whats on the screen fine so I would like my phone to stay dimmed whilst using it to save battery, any idea how this can be done?

thanks will check it and hope it maintains colours.
try to search brightness level in the market
it can dim the brightness a bit lower than 0 (as written in display setting)
Adj Brightness. Set it to 2.
Hi, I see there are more and more mods and tweaks designed to help boost battery life. Any efforts like this are really helpful and I'm glad of them.
The biggest use of my battery however is the screen, how about your phone? We have all tried turning down brightness, leaving automatic brightness on etc. but I really think any significant progress that we could make is through changes to how the screen works. Ultimately, I think perhaps the screen resolution and the Sony tweaks like Bravia are too powerful for the size of this battery to cope. Does anyone think something else may be the problem?
I haven't noticed any difference when turning Bravia off. What else could we do?
I use root dim
Always keep bravia engine off ( I dun find any difference to b true)
And I have a brightness bar in notification drawer to adjust brightness quickly
I didn't know about that app, I'll give it a try now. I notice that when you turn down the brightness to around 30% or less that the backlight completely turns off? I bet that is the real killer of the battery.

I use root dim
Below 10% I cant sew anything
It saves battery coz it decreases brightness
What night mode is that it adds a grey shade
Night mode has no effect on brightness
And dim brightness means battery saved
As per the title, is it possible to stop the screen brightness going into 'boost' mode when outside, whilst keeping autobrightness on? Often when it's not that bright outside, the screen defaults to maximum brightness which washes it out and wastes battery
This is typically only possible with a custom kernel.
